Substantiation of the effectiveness of the hydro-steam turbines application in mine power complexes for excess heat recovery

Abstract

The main problems connected with an increase in the performance efficiency of the mine power complexes, should include issues of rational use of fuel in power facilities, as well as the maximum consumption of produced thermal and electrical energy. One solution to this problem has been proposed to use in schematic solutions the reaction-type hydro-steam turbine for excess heat recovery of and generation of additional electrical energy. The condition has been set in the article for the choice of the configuration of a hydro-steam turbine nozzle with a high efficiency of energy conversion, as well as the variants have been studied of principle schemes for energy complexes: the scheme for a power facility, consisting of a gas-reciprocating module, on the shaft of which a module with a hydro-steam turbine is set, as well as the scheme for a module placement of back pressure turbine and hydro-steam turbine on the same shaft with a gas-reciprocating module. A comparative analysis has been performed of energy efficiency of the proposed principle schemes for the energy complexes.
